Jessica Chapman is an experienced attorney with a diverse and distinguished career spanning 20 years. A proud graduate of Louisiana State University, Jessica earned a bachelor’s degree in mass communications in 2004, graduating cum laude. She then continued her studies at LSU’s Law School, where she graduated in 2007 in the top 25% of the class with a Juris Doctor degree and a bachelor’s in civil law.

Jessica's legal career has spanned multiple sectors, starting with five years as an Assistant Attorney General at the Louisiana Attorney General’s Office, where she honed skills in general liability litigation, advocating for the state and its employees in a variety of complex matters. She then spent five years focusing on title insurance and curative litigation, representing national title insurance companies and lending institutions in complex litigation matters and gaining deep expertise in property law and dispute resolution.

Prior to joining the Carter Firm, Jessica served as in-house litigation counsel for a major health insurance payor for seven years, where she played a key role in resolving complex healthcare disputes. She advised on pre-litigation matters, helping to navigate reimbursement disagreements, contractual disputes, and regulatory challenges before they escalate.

In addition to her legal career, Jessica is committed to giving back to the community. She serves on the board of directors for the Baton Rouge Chapter of the National Charity League, volunteers at St. George Catholic School and St. Joseph’s Academy, and is a member of the Karnival Krewe de Louisiane.
